Au contraire, Blackadder. UPDATING says to run either of 

portmaster -r jpeg*

OR

portupgrade -fr graphics/jpeg

It says nothing of pkg_delete.

pkg_delete -r <package> - recursively delete <package> and all others that 
depend on it.

Yep, because pkg_delete removed their entries from the registry.

That's going to be the best bet, yes.

You could try installing prebuilt packages, but they might not all have been
updated yet to use the new version of jpeg.

Read the relevant entry again. It mentions nothing about running pkg_delete.
